1 ) Define Operating System (OS) System Processes:

1 ) Define Operating System (OS) System Processes:, - In the context of the Operating System,, - a system process is an instance of a computer program, - that is currently being executed by the CPU., - It is a fundamental unit of work in a modern OS , - and includes the program code,, - its associated data, execution context (CPU registers),, - and a dedicated address space within memory.

2 ) What are the two processes that system processes are broadly classified as:

2 ) What are the two processes that system processes are broadly classified as:, - OS/Kernel Processes., - User Processes.

3 ) In regards to system processes, define the classification of OS/Kernel Processes:

3 ) In regards to system processes, define the classification of OS/Kernel Processes:, - These are executed on behalf of the OS kernel, - and manage essential system resources, - (e.g., memory management, scheduling, I/O handling)., - They typically run with the highest privileges.

4 ) In regards to system processes, define the classification of User Processes:

4 ) In regards to system processes, define the classification of User Processes:, - These are executed on behalf of a user,, - running applications like web browsers , - or word processors., - They run at a lower privilege level.

5 ) What are the key security mechanisms enforced by Operating System (OS) system processes?

5 ) What are the key security mechanisms enforced by Operating System (OS) system processes?, - Process Isolation., - Privilege Management., - Access Control.

6 ) In regards to key security mechanisms enforced by Operating System (OS) system processes, define the Process Isolation mechanism?

6 ) In regards to key security mechanisms enforced by Operating System (OS) system processes,, define the Process Isolation mechanism?, - The OS kernel enforces process isolation, - —a core security concept. , - This mechanism ensures that one process , - (and its associated data) , - cannot interfere with another process, , - preventing a vulnerability in a user application, - from compromising an , - entire system process or the kernel.

7 ) In regards to key security mechanisms enforced by Operating System (OS) system processes, define the Privilege Management mechanism?

7 ) In regards to key security mechanisms enforced by Operating System (OS) system processes, , define the Privilege Management mechanism?, - Every system process , - is executed with a specific set of privileges (or user identity)., - Processes that perform critical OS functions, - (like a service process) , - run with high or "system" privileges., - If a threat actor exploits a flaw in a low-privilege application,, - they will attempt privilege escalation , - to gain the authority of a system process,, - thereby taking full control of the host machine.

8 ) In regards to key security mechanisms enforced by Operating System (OS) system processes, define the Privilege Management mechanism?

8 ) In regards to key security mechanisms enforced by Operating System (OS) system processes,, define the Privilege Management mechanism?, - The OS uses the process's identity , - (the user or service account running the process), - to enforce Access Control Lists (ACLs). , - For a process to read or write a sensitive configuration file , - or access a peripheral, , - the OS first checks if the process's identity has the required permissions. , - Monitoring a process that suddenly attempts, - to access resources outside its normal scope , - is a key indicator of a security incident.
